IMPROVED DEVICE FOR EXTRACTING STUMPS.

Specification forming part of Letters Patent No. 50,244, dated October 3, 1865.

To all whom it 'may concern:

, Be it known that I, E. C. HAsEEIoK, ofLake Village, in the county of Belknap and State of New Hampshire, have invented a new and Improved Device for Extracting-Stamps and' Elevatin g land Conveying Heavy Bodies; and I do hereby declarethat the followingis a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying' drawings, forming part of this specifica- 8vo., and conveying them when lelevated and l retained in a suspendedstate to the, place designed for them.

This invention consists in the employment or use of a hydraulic apparatus" similar to that used in the hydraulic press, placed upon a strongly-built carriage andl arranged with a water-tan k, and havin gthe axles ofthe carriage provided with screw-jacks, all arranged in such a manner that the desired work may be performed with but .little laborand with great facility.

The carriage may be constructed of a platform, A, of hard wood (oak would be a good 1material) resting upon holsters a a, which are supported by the axles B B, the front axle working on a king-bolt to admit ot' the turning of themachine. C is the draft-pole'attached to the front axle, and D represents screw-jacks, which are connected two to each axle near their ends. These screw-jacks are' composed of standards b, provided with internal screw-threads, in which screws c are fitted and work, the up'- per ends of the screws being tted in metal bands d, which encompass the axles, the screws being allowed'to turn freely in their bands. -By this arrangement it will be seen that the carriage may be raised (jacked up) at any time so as to relieve the wheels E", and which is most generally necessary in lifting heavy bodies or in extracting stumps, especially at the commencement of the operation where the articles are fixed, like stumps in the earth, as the carriage has a great force to resist under the action ofthe power applied to loosen the same.

E represents a water tank or reservoir attached to one side of the carriage, and F is a cylinder which is firmly secured on the same, and has a pump, G, at one side of it, the sucti. .-tube ont' the pump descending into the tank E. l'

H is a discharge-pipe leading from cylinder F, and I is a follower placed in F.

' J represents what maybe termed a liftingframe, the same being composed of two rods, e e, which pass vertically-through the body or platform A at opposite sides oi' the cylinder F, and are connected at their lower ends by a cross-piece,j`, having a hook, g, secured in it. The upper ends of the rodse e have screwthreads cut on them, on which thumb-nuts h are fitted, and i is a cross-piece placed on said rods underneath the nuts h. The upper end of the cyliuderF is provided With'a horizontal flange, j, through which the rods e e pass loosely,.said flange servin g as a guidefor the rods. A

The discharge-pipe H of cylinder F is provided with a fadcet, k, and when the device is adjusted for use thecross-pieceirests on the top of the follower I, the hook g being adjusted to the desired height by turning the nuts h h. The chain is placed around the stump or other article to be raised, and the slack of the chain taken up by turning nuts h, and the tank E being filled with water and the screws of the jacks l) turned so as to take wholly or partially the weight ofthe carriage oit' from the wheels, the operator works the pump, thereby drawing the water from tank E and forcing it into the' lower part of cylinder F underneath the fol lower I, which is raised thereby, and with it the frame J and the body attached to the hook g,

The elevated body may be retained in an elevated position by means of pins l inserted in holes m in the rods e underneath the crosspiece t' and above the ilangej of-cyllnder-F. The body while thus elevated may be conveyed to the place. designed for it, the jacks YD being previously screwed down so that the ear-4 riage may rest entirelyupon its wheels, 'lhe body may belet down gradually from its suspended positionby allowin g the water to escape gradually from pipe H into the tank E.

This devieemay be operated with the greatest facility, and Very heavy bodies may be raised by it and transported where desired. The jackserews when not in use may be turned up and held in a-position out of the way by means of ohaiusarranged in any proper manner. In case a greater elevation 'is requiredthan the follower alone'will admit of, blocks K (Figs. 3 and 4) may ne inserted between the follower and the cross-piece t', the' follower being let down at the termination of its upward movement by dis-v charging the water from F 'through B, the

frame J meanwhile being held by inserting the pins l i-n the holes m of the rods e.

Having thus described my invention, I claim as new'and desireto secure by Letters Paten t The'applieation to a carriage or mounted truck of sa hydraulic apparatus constructedI and arranged' as described, with a water-tank 'and a lifting-frame, or its equivalent, for the
